TYCOON TURNAROUND: Just a few years ago, flamboyant Brazilian billionaire Eike Batista was boasting that he'd soon be the world's richest man. But now his once high-flying OBX oil company has filed for bankruptcy protection and faces possible liquidation. There are concerns that his ship building company may also quickly fall into bankruptcy.
BILLIONAIRE NO MORE: Batista's fortune has reportedly dwindled to less than 1 percent of the $34.5 billion that Forbes magazine estimated he was worth in early 2012.
SPUTTERING BRAZIL: His troubles may be a new sign that the country's economic slide will continue amid a downturn in world commodity prices and Brazilian consumer spending.
